More Information
Summary:A fingerprint sensor is provided and includes a substrate; sensor electrodes arranged in a matrix on the substrate; switches coupled to the sensor electrodes; a control line drive circuit; a signal line drive circuit; signal lines coupling the signal line drive circuit to the sensor electrodes through the switches; control lines transmitting a selection signal to the switches from the control line drive circuit; and a sensor drive electrode surrounding the matrix of the sensor electrodes, wherein a distance of the sensor drive electrode from a surface of the substrate is larger than a distance of the sensor electrodes from the surface of the substrate.
